The AppImage for StarUML currently crashes under Manjaro and Arch Linux due to including an old version of the harfbuzz library.

I have 4K monitor and the GUI text is too small I would like to increase it.

Save last main windows size and restore it when program is opened. Windows 10.

i used bitbucket a lot, I'd love to be able to install extensions from there

I use many Diagramms and arrange them on the left handside "Working Diagrams". After closing and re-opening the file, the order of the "Working Diagrams" is set to the order you opened the diagrams, and not the one you had on arranging them manually. I would like to have the order of them persisted (should not be a big deal, shouldn't it?).

This has been requested many times. It was supposedly already fixed in version 3.0, according to [this issue](https://staruml.uservoice.com/forums/245359-feature-request/suggestions/14948286-diagram-background-color). But it is certainly not fixed in version 3.1.

For me it's an accessibility issue. Your otherwise excellent program is rendered (no pun intended) unusable, because 2/3 of the screen is a painfully glaring white.

I literally select ever class and interface and enable this option. Would love if I could configure this to just be on by default when I create new class or interface elements.

Imagine being able to assigned user-defined tags to model elements and then filter those model elements in a diagram by creating an expression based upon tags. These tags could represent anything you want like subsystems, user roles, sprints, you name it. This was an ability of the old OOATool from Object International back in the late 1980's.

On my high def screen the toolbar fonts are far too small to read. Can we add a field to set the size?

StarUML does not allow an artifact instance to deploy to a node instance.

An error "Invalid connection (UMLDeployment)" is displayed.

See https://www.uml-diagrams.org/deployment-diagrams-reference.html

Please let us change diagram background color, which is now white. White is too aggressive for eyes in dark environment ... I would prefer to change to some greyish tone.

needed for Decision Shape in Activity Diagram

so class can be root for multiple subtrees each representing different aspect of generalization

We need a scrollbar to zoom in and zoom out better and if it's positioned in the status bar it would be great.

If for example a class is removed from the model the attributes usind it as a data type show as if it is still in the model.

Currently there is no way to get back the associations which have been removed from the diagram, but not from the model

Currently attempt to open another model fails almost every time in error (OSX). Only indication of that is a quick error message which is shown just briefly and easy to miss. After failure StartUML opens previous model which could lead to loss of data if user doesn't notice it. Second attempt to open the model works always.
